IMPROVEMENT IN BABIES SAFETY-CHAIRS.

Specification forming part of Letters Patent No. 202,991, dated April 30, 1878; applicationiiled I February 8, 1878.

To all whom it may concern.-

Be it known that we, EDWARD GHRISTMAN and JOHN CALDWELL, of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and Improved Babys Safety-Chair, of which the following is a specification:

The object of our invention is to furnish a safe and adjustable chair for the use of infants, and whereby all accidents to the child consequent upon its own pushing, kicking, or attempt to rise or slip down are prevented.

The invention will first be described in connection with the drawing, and then pointed out in the claim.

In the accompanying drawing, Figure 1 represents a front view of our improved safety baby-chair with the front shield locked. Fig. 2 is a front view of the same with the shield open. Fig. 3 is a side view of the same clamped to a table, and partly broken out to show the construction. Fig. 4 is a detail view, explanatory of the mode of attaching the adjustable foot-board.

Similar letters of reference indicate corresponding parts.

In the drawing, A is the back, and A are B are the front legs. 0 is the seat. D are arms. E are the upright front rounds of the arms D, and F the other rounds ofthe chair. G is a screw-clamp, provided with a perforated extension, g, by which it is fitted on one of the upright front rounds E, so that it can be moved up and down on the said round, and thus adjusted to the height of a table or other article of sufficient stability, and fastened thereto by the screw 9, for securing the chair against being upset by any pushing or kicking by the child, while allowing of full freedom to swing the chair on the vertical round E in the hole of the clamp G, and place it in any desired position while it is thus secured by the clamp G.

H isastrap, of two parts, connected together by the buckle h, and has a button-hole in either end, for fastening it on studs or buttons 0 on the opposite sides of the seat 0. The strap H is buckled over the lap of the infant to prevent it from rising in the chair.

I is a board fastened between two front legs, B, of the chair below the seat 0, and provided with two vertical rows of horizontally-opposite holes, 6, in which the foot-board J is secured by studs j, and adjusted to a suitable height for supporting the feetof the child without cramping its legs.

The form of the holes 6 is that of a circle, having a downward'extending notch or slot of less width, into which latter the shank of the stud j is placed to rest, after introducing the head of the stud j through the circle of the hole i, so that when the shank is in position in the said notch the head of the stud j will project behind the board I on the sides of the shank, and thus prevent the latter from slipping out of the notch. When the studs of the foot-board are in the notches of the holes 11 the downward-projecting flanges j of the fo0t-b0ard J bear against the board I and keep the foot-board in a horizontal position.

K is a shield, hinged to one of the front legs B, and curved to inclose the foot-board, against which it'may be closed and locked by a button or latch, L, (on the front leg B laterally opposite to that to which the shield K is hinged) and a catch, k, on the end of the shield K.

The shield K, when closed and latched, prevents the child in the chair from falling by slipping down off its seat.

We do not limit ourselves to the exact form of any of the parts here shown, as they may be varied without departing from our invention.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent A babys safety-chair having the clamp G, the strap H, the foot-board J, and the shield K, arranged and made adjustable as and for the purpose specified.
